3Iay 20th. 

 Vice-President Wetherill in the Chair. 



Dr. Leidy remarked that in a recent visit to Dr. Wilson, near Newark, Dela- 

 ware, while rambling in a neighboring wood, upon turning over a log, he discov- 

 ered a mole cricket, (Grillo-talpa America?ia,) standing very quietly at the mouth 

 of a hole. Upon taking it up, the animal exhibited no signs of movement, though 

 perfectly fresh and life-like in appearance. He took it home and next morning 

 examined it, and found it still presenting no signs of life. Every part of the in- 

 sect was perfect, not even the antennas being broken. Upon feeling it., it was 

 very hard and resistant, and on making an incision through the thorax, it exhaled 

 a fungoid odor. The insect had been invaded with a parasitic fungus, which 

 every where filled the animal, occupying the position of all the soft tissues, even 

 into the tarsal joints. It formed a yellowish or cream-colored compact mass, 

 and in the abdomen enclosed in its centre the stomachal teeth of the in- 

 sect. 



Examined microscopically, the fungus matter was found to consist of a myce- 

 lium of filaments for the most part simple, but occasionally branched, and ellipti- 

 cal or globular sporular bodies, averaging the l-2333rd in. in diameter.
